Syntax error. Expected token=')

Error message

Syntax error. Expected token=')' :<token>

What it means

Parser guard in checkEndToken: the next token read from the Oracle connection descriptor was not the singleton ')' end-object token, i.e. extra or unexpected content appears where the closing parenthesis of an address/description block should be.

Solutions

1. Fix the descriptor so each (KEY=VALUE) block closes with ')' exactly where the grammar requires
2. Remove stray tokens or misplaced keywords before the closing parenthesis
